This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application Ser. No. 61/478,770, filed Apr. 25, 2012, which is expressly incorporated by reference herein.
BACKGROUNDThe present disclosure relates to furniture, and in particular, to folding furniture. More particularly, the present disclosure relates to a folding chair and a folding bench.
SUMMARYA folding chair in accordance with the present disclosure includes a frame, a seat bottom, and a seat-bottom support. The seat bottom is movable relative to the frame between an unfolded use position and a compact folded storage position.
In illustrative embodiments, the seat-bottom support is retractable and includes first and second gatefold leg units. The first gatefold leg unit is coupled to one side of the frame using a first hinge included in the folding chair. The second gatefold leg unit is coupled to an opposite side of the frame using a second hinge included in the folding chair. When the gatefold leg units are unfolded, they underlie and support the seat bottom in its unfolded use position.
In illustrative embodiments, seat-bottom retainers are coupled to each of the first and second gatefold leg units and are configured to guide the seat bottom as the seat moves downwardly into the unfolded use position and retain the seat bottom in the extended use position. A first seat-bottom retainer provides lock means for interconnecting one side of the seat bottom to the first gatefold leg unit to cause movement of the seat bottom to be blocked in response to engagement of the lock means by a user in the field. A second seat-bottom retainer provides lock means for interconnecting an opposite side of the seat bottom to the second gatefold leg unit to cause movement of the seat bottom to be blocked in response to engagement of the lock means by a user in the field.
In illustrative embodiments, the first seat-bottom retainer also provides alignment means for aligning the seat bottom on the first gatefold leg unit to cause the lock means to be arranged so that a user may engage the lock means to block movement of the seat bottom away from the unfolded use position. The second seat-bottom retainer provides alignment means for aligning the seat bottom on the second gatefold leg unit to cause the lock means to be arranged so that a user may engage the lock means to block movement of the seat bottom away from the unfolded use position.
Additional features of the present disclosure will become apparent to those skilled in the art upon consideration of illustrative embodiments exemplifying the best mode of carrying out the disclosure as presently perceived.
